Question

A calorie is a unit of heat or energy and it equals about 4.2j where 1j

Answer 1

Explanation:

A calorie is a unit of heat or energy and it equals about 4.2 J, where 1 J = 1 kg m^(2) s^(-2). Suppose we employ a system of units in which the unit of mass equals alpha kg, the unit of length equals is beta m , the unit of time is gamma s. Show tthat a calorie has a magnitude 4.2 alpha^(-1) beta^(-1) gamma^(2) in terms of the new units.
